While his had always felt a connection to Oghma, it wasn't until he met his partner, E'on, that he decided to become a priest. The both of them has spent many hours in study together. As E'on is deaf and Heris has never been comfortable with loud environments, the two are very happy just reading or writing together.
Heris is often uncomfortable around people and might miss some social cues, especially if he's not paying close attention to every detail. This also leads to him not being very fond of any context with too much sensory input. He is very friendly and appreciates those who put in the effort to understand what he actually means. Texts are soothing and Heris has spent a lot of time reading and can almost always direct anyone to the correct part of the library at the Jolethai temple of Oghma, or even where to find a volume at a different location.
